PVE with antivirus
- Thread starter NPK
- Start date
It cannot affect the license as that is AGPL3 
. Maybe use a (free) support ticket (or an email) to ask the Proxmox sales office directly to tell you if your specific antivirus software impacts the support contract? I don't think the volunteers (which includes the technical Proxmox staff) on this forum can give you a definitive answer for any software in particular.

My question would be, why would you need an antivirus on a host ? I understand having antivirus inside a VM.
In my opinion, you're asking the wrong question. Instead of asking whether antivirus software could cause problems on the host, you should first ask whether it is needed there at all. Only if you come to the conclusion that it is needed your original question would become relevant.
Personally, I see no reason to run antivirus software on the host system, why would you? Antivirus is primarily intended to scan user data, and user data has no place on a virtualization host. As long as you only use software provided by the official repositories (Debian and Proxmox) and don’t install anything sketchy, you simply don’t need an antivirus scanner on the host.

In order to answer this question seriously, we would need to know exactly which antivirus product OP intends to install.
@NPK If you're talking about a classic AV scanner like ClamAV:
I’d consider that mostly useless on a virtualization host, because normally you wouldn’t upload random files to the host itself. And if you do upload untrusted files to the host, then you’re already in unsupported territory, and the activities that lead you to believe you need antivirus on the host are probably the much bigger issue.
If by “antivirus” you actually mean general security hardening or third-party security tools, they'd likely need to know which specific software you’re referring to. In that case, it would probably be best to open a support ticket and ask the Proxmox team directly whether they support the tool you want to use — or consider proper security consulting for Proxmox and Linux in general.
Long story short: Your question is too vague to answer with a simple “yes” or “no.” And if I had to guess, I’d say this is more about checking some compliance boxes for management than about actual security.

I am not convinced of the supreme benefit of adding an antivirus to a hypervisor; it is really more a question of ticking a box, yes.
It can be F-Secure, ClamAV, or another one. I haven't seen any official statement from Proxmox on this subject, that's why I'm asking here - and I don't have active subscription support at this time.
I can't imagine ClamAV being a problem for Proxmox or their support, as it is a standard Debian package. Best to contact Proxmox office or sales directly for official answers to your questionnaire: https://proxmox.com/en/about/contact
I'm with you.
But the argument is weak: there are 64000 packages in Trixie - probably not all of them are harmless for PVE...

Linux is an inferior antivirus platform. If you want to run your antivirus really well, the best bet is to install Windows.
Saying what?
I have no idea what that means, an anti virus is only applicable to its host operating system especially if monitoring RAM. a windows av is of no purpose if you're running PVE and vice versa- there is no such thing as "antivirus platform"
Windows is a largest virus platform. Therefore it is also the largest anti-virus platform. Even Linux anti-virus products mostly check for Windows viruses. Which makes sense if you're serving files to Windows users. On a Linux-based hypervisor it is just useless overhead.
Yes, I am aware that certain standards like the US Government's STIG's, require anti-virus on Linux servers regardless of function. Doesn't make it any less dumb, just easier for non-technical people to verify.
